AI Technical Summary
Technical Problem
Existing microwave ablation needles are inefficient in cooling and cannot cool quickly, resulting in possible damage when taken out and causing damage to normal human tissues.
Method used
A microwave ablation needle is designed, which is equipped with a catheter on the outer side of the ablation needle body, and cools the catheter through the circulating water channel, and after the microwave ablation is completed, the tip of the ablation needle body is brought back into the catheter to avoid harm to normal tissues of the human body.
Benefits of technology
The cooling efficiency of the ablation needle body is improved, and the damage to the normal tissue of the ablation needle tip with a higher temperature is avoided, which enhances the safety of use.

Abstract
The utility model discloses a microwave ablation needle for hemangioma and vessel malformation treatment, and belongs to the technical field of medical instruments. The microwave ablation needle comprises an ablation needle body and an ablation needle tube, a catheter is arranged at the front end of the ablation needle tube, the ablation needle body is coaxially and slidably sleeved with the catheter, and cooling assemblies used for cooling the ablation needle body are arranged in the ablation needle tube and the catheter. A first mounting groove is formed in the rear end of the ablation needle tube, and a limiting assembly used for limiting the ablation needle body is arranged in the first mounting groove. According to the microwave ablation needle, through the arrangement of the catheter, the cooling efficiency of the ablation needle body can be improved under the condition that the microwave ablation effect is not affected, and the tip end of the ablation needle body can be collected into the catheter after microwave ablation heating is finished; the high-temperature tip of the ablation needle body can be prevented from hurting normal tissues of the human body, the limiting assembly can prevent the ablation needle body from moving front and back in the using process, and safety is higher.
